NY keeps nibbling away at L.A.'s movie-making supremacy (they still have a ways to go). Steiner Studios, Brooklyn's largest studio and part of what they call "Hollywood East," plans to expand to 600,000 square feet by renovating a seven-story building in the Brooklyn Navy Yard. Steiner is where "Spider-Man 3" and "Inside Man" were made. The number of film, TV and video productions in the city reached an all-time high last year, in part because of tax incentives to film in NY. NY Daily News
